Application filed September 27, l927 Serial No. 222,819.

The object of my invention is to provide a dispenser for dispensing of semi-hard substances such as soap, vanishing cream, tooth paste and the like, which ordinarily come packed in collapsible tube containers where y small amounts of the contents of the collapsible container may be dispensed ordinarily.

Still a further object is to provide an air tight container adapted to have a collapsible tube filled with semi-hard contents placed within the container so that when the container is filled with air, there will be a tendency of the air within the container to collapse the tube and force the contents therefrom through a discharge nozzle or valve which valve is adapted to be manually operated.

Still a further object is to provide a valve controlled passageway whereby air may be forced into the air tight container for building up a pressure therein.

Still another object is to provide a manually operable valve or nozzle adapted to be normally held in closed position by the contents from within the collapsible tube.

A further object is to provide a pump ele ment for forcing air into the container so that the collapsible tube may be automatically or by air pressure, collapsed for forcing the contents therefrom.

With these and other objects in view my invention consists in the construction, ar-

rangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a side view of my dispenser with parts shown in section to better illustrate the construction thereof.

Although the invention is susceptible of a variety of embodiments, it is unnecessary to fully describe and illustrate more than one in order to give a full understanding I of the invention both from its structural and functional standpoints. Accordingly, I have illustrated a preferred anddesirable embodiment of the invention in the accompanying drawings in which A represents the base of my dispenser and 10, a tubular container closed at its upper end and open at its bottom end.

The base A is formed with an interiorly screw threaded socket 12 adapted to receive the lower end of the container 10. The container 10 is formed adjacent its lower end with screw threads 14 adapted to coact with screw threads of the socket 12. A suitable washer 16 of compressible material is adapted to be received within the socket 12 andto have the lower end of the casing 10 rest thereon, thus forming an air tight connection between the container 10 and the base A.

Within the center of the socket 12 and formed as part of the base A is an upstanding neck 18 having a central screw threaded opening 20 therein. A passageway 22 extends from the screw threaded openin 20 through the base A and through a hu 24 formed as part of the base A all clearly illustrated in Figure 1 of the drawings.

Mounted upon the base A and within the 10 container 10 is a collapsible tube 26 adapted to contain any semi-hard substance suclpips shaving soap, vanishing cream or the 11 e, normally dispensed in so-called collapsible tubes. The collapsible tube 26 is normally provided with a screw threaded neck 28 for ordinarily containing a cap or closure memr. I make use of the screw threaded neck 28 and screw it into the screw threaded opening 1" 20in the member is. 'The collapsible tube 1 26 is thus mounted'upon the base A and within the container 10. The contents of.

the tube 26 is permitted to pass through the -opening122 as will hereinafter be more fully passageway 22 formed in the base A.-

' Within the body portion 30 I- provide a valve seat 36 adapted to have the valve member 38 rest thereagainst for closing the passageway within the. body member 30. A valve stem 40 projects throu h the body member 30 and as a knob or ger engaging piece 42 secured thereto by means of screw threads or the like.

The inner surface of the valve member 38 is substantially cup-shaped or dished as at 44. g It will be noted that the substance to be dispensed will normally fill the passageway 22 and that portion of the passageway rearwardly of the valve member 38. 'The substance will tend to force the valve member 38 to its seated position.

An ordinary'pilmp C'of any suitable kind is used for charging or filling the container 10 with air. This is accomplished by a needle valve construction-46 formed in the base- A. The needle valve and its adjusting nut 48 are moved to open' position as shown in Figure 4 of. the drawings and thereafter, the pump is employed for forcing a considerable amount of air into the container 10 to build up a pressure therein.

After the container 10 has been charged with air then the needle valve adjusting nut 48 is moved to closed position. The compresed air within the container'lO tends to exert a p'sessure upon the colla sible tube 26 tendin collapse it and at t e same time, force e contents therefrom outwardly.

The valve member B may be ogerated by moving the valve stem 40 inwar this time a portion or small amount of the contents from the tube 26 will pass around the valve member 38 and be discharged through the nozzle 32. The pressure of the p ontents against the valve member 38 will when the valve stem 40 is released, immediately move it to closed position.

It will be noted that by pushing the valve member 40 inwardlya short distance, the contents from the 'tube will be dispensed. In F igures'7 to 11 inclusive, I have shown the containers as arranged in series, that is,

where more than one container is used so I, that various commodities may be dispensed.

and is in comly and at.

giaced upon the base G, will cause them to I securely heldin position. Y

The air tight connection is formedbetween the base and the containers 54 washers or the like 16. Within the base in a downwardly extending portion 60 thereof, I provide a cylinder 62 having a iston 64 therein. The piston 64 is connecte to a stem 66 having a finger engaging piece 68 thereon. a

The base D is hollow as at 70 and has communication with the cylinder 62'through asmall passageway 72 and valve element 74. The inner end of the stem 66 is ointed as at 76 and is adapted to seat itsel within a ortion of the valve and serves as a closure or the valve.

. Thecylinder 62 is in communication with atmosphere through the small pass es 78. The operation of t e ump element w ich is built in the base 0, orces air through thevalve 74 and into the hollow ortion 70 of the base D and fills each of t e containers 54 with air. Collapsible tubes containing any suitable semi-hard substance are mountmanner as has heretofore, been described in connection with the collapsible tube 26.- and its connection with the base-A.

' Practical operation.

In the practical use of my .dispenser it is necessary to first remove the container 10 or the containers 54 and (place a collapsible tube with its discharge en down u n the bases A or D and connect them to t bases A or D. The containers 10 or 54 are then mounted upon their respective bases so that an air tight connection is had between such containers and the bases.

The containers are then filled with air in any suitable manner so that the tubes within the containers tend to collapse due to the outside pressure thereon thus tending to ex el the contents from the casing.

' anual operation of the valve member or nozzle B will permit the contents to be discharged. It will be noted that. the containers may be mounted in single units or ma be arranged in multiple units.-

ariouscommodities such as shaving soap, .tooth paste, vanishing cream and thelike may be dispensed from' collapsible tubes 1 100 ed upon the base C in substantially the same spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reason ably included within their scope.

I claim as my invent-ion:

1. A dispenser of the character described comprising an air tight container, a collapsible tube containing semi-hard substances mounted in said container, said container having a passageway therein one end of which is open to atmosphere and the other end of which is in communication with the discharge end of said tube, means for filling said container with compressed air whereby a tendency to collapse said tube is constantly maintained within the container, a portion of thetube serving to cut off communication between the interior of said container and said passageway for making said container an air storage tank and a valve in said passagewaynormally held closed by the pres sure of said substances thereagainst.

2. In a dispenser, a collapsible tube having contents to be discharged therefrom, a

container surrounding said tube and spaced therefrom, means for constantly exerting a pressure upon said tube within said container for normally tending to collapse said tube and discharge the contents therefrom, and means for withholding the discharge of the contents against such normal tendency, said last means when operated allowing the contents to be discharged in a charge and thereafter closed by the contents.

3. A dispenser of the character described comprising an air tight container, a collapsible tube containing semi-hard substance mounted in said container, said container having a passageway therein one end of which is opened to atmosphere and the other end of which is in communication with the discharge end of said collapsible tube, means for filling said container with compressed air whereby a tendency to discharge the contents of the collapsible tube is maintained within the container, a portion of the collapsible tube serving to cut off communication between the interior of the container and the passageway for making said container an air tight storage tank and a valve in said passageway normally held closed by the pressure of said substance thereagainst.

4. Ina dispenser, a collapsible tube having contents to be discharged therefrom, a container surrounding said collapsible tube, means for constantly exerting a pressure upon said collapsible tube within said container for normally tending to discharge the contents therefrom and means for withholding the discharge of the contents against such normal tendency, said last means when operated allowing the contents to be discharged in a charge and thereafter closed by the contents.
